Tool that activates aura. How can I fix?

Hello, I have problem with my scripts. I tried to start making it, but my scripts didn’t work.

But. I wanna make Tool that activates Aura! Can you help me? (dm me rice#7694 (discord))

And i mean: Equip tool - Click on screen - And aura on your all body

Assuming that by Aura you mean a particle effect of sorts, you could just have the tool find the players HumanoidRootPart and adding a particle emitter to it, and for multiple uses checking if theres already a particle emitter inside of it

Example:

Tool = script.Parent
ParticleEmitter =
Tool.Equipped:Connect(function()
	if Tool.Parent.HumanoidRootPart:FindFirstChildOfClass("ParticleEmitter") then
		ParticleEmitter.Enabled = true
	else
		ParticleEmitter = instance.new("ParticleEmitter")
		ParticleEmitter.Enabled = true
	end
end)

Tool.Uneqipped:Connect(function()
	ParticleEmitter.Enabled = false
end)
